Broom provided with a regulator for controlling the flow of floor cleaning and treatment products

ABSTRACT

The present invention concerns a broom provided with a regulator for controlling the flow of floor cleaning and treatment products.  
     Said broom is characterized in that a tubular appendage ( 29 ) provided on the bottom of a reservoir ( 3 ) for the discharge of liquid has an opening sufficiently large to allow it to be easily cleaned of incrustations and deposits that result from the use of dense or semi-dense fluids, such as floor waxes, and is structured continuously with the bottom of the reservoir ( 3 ), so as to resist any interventions resulting from possible cleaning of the tubular section (FIG.  10 ).

[0001] The present invention relates to a broom provided with aregulator for controlling the flow of floor cleaning and treatmentproducts.

[0002] In the past, floors have generally been cleaned by hand, usingmops. The sequence of activities comprised, respectively, washing,drying, and polishing. The materials involved included liquiddetergents, pure water without additives, and wax emulsions.

[0003] In the case of large floor areas, the mop was used in conjunctionwith a stiff broom head. The original combination of mop and stiff broomhead has been gradually perfected, resulting in true brooms, consistingof a shaft and a support provided with a shaft carrier and equipped, onits lower section, with suitably attached mop heads. The requisiteamount of liquid (at the beginning of the process) or wax (at the end)were poured by the operator directly on the floor from variouscontainers. They were then spread across the floor using mops or stiffbrooms or a series of brooms equipped with a shaft and a support with anunderlying softer element.

[0004] Because it was difficult to easily and uniformly spreaddetergents or polishing products over floors, brooms appeared on themarket that were equipped with a bottle holder or their own reservoirs,which were connected either to the bottle holder or to attachedreservoirs containing specific devices for regulating the flow of fluids(liquids, waxes, etc.) contained in those reservoirs.

[0005] Other brooms subsequently appeared on the market and these wereprovided with a reservoir mounted coaxially with respect to the shaftand connected, at the lower part of the reservoir, to a small flexibletube that descended toward the floor after traversing, at a certaindistance from the floor, the shaft structure.

[0006] Among brooms now present on the market, stopping and regulatingthe flow of fluid contained in the reservoir, which passes through thesmall tube, is based on compression of the small tube, which is effectedalong a predetermined section of tube using appropriate means.

[0007] Control of the compression of the small tube is effected byacting on a control knob located on the top of the shaft, which, bymeans of a wire (using tension) or rod (using pressure), counterbalancesthe action of a spring, which, during the period the broom is not inuse, maintains the small tube in a compressed state.

[0008] Brooms sold on the market having a reservoir mounted on theshaft, where regulation of the flow of liquid from the reservoir isrealized through compression of a section of small tube made of aflexible material and connected to the lower part of the reservoir, aremade as follows.

[0009] These brooms consist of:

[0010] a reservoir configured with an opening and mounted coaxially onthe shaft, whose outside wall, extending the bottom of the reservoir,rises along the center part, forming a tube that surrounds the shaft

[0011] a small tube made of flexible material connected to a tubularappendage at the bottom of the reservoir and descending toward thefloor, traversing the broom shaft

[0012] a shaft that supports a reservoir and is connected, by means of apivot, to a base plate equipped with a piece of fabric

[0013] a control knob on the top of the shaft grip, which is connectedto a device for compressing the small flexible tube where it crosses theshaft (or an extension of the shaft)

[0014] a spring activated device, which, when at rest, maintains thesmall flexible tube issuing from the reservoir in its fully compressedstate at the point where it crosses the shaft (or an extension of theshaft)

[0015] a cover in the shape of an inverted cup, provided with a centraltubular cavity running along the shaft.

[0016] The interior of the cover is provided with an edge designed tomake contact with a corresponding outside edge of the reservoir.

[0017] The cover is provided with a skirt along the upper outer part,near the shaft.

[0018] The lower outer part of the cover is configured in such a waythat, once the cover is lifted upward, it is elastically engaged by thelower part of the shaft grip and retained in place. This enables theoperator to use both hands without having to hold the cover open whileengaged in activities involving the mouth of the open reservoir.

[0019] To initiate the flow of liquid from the reservoir downward, theoperator interacts with the control knob located on the top of the shaftgrip by moving said control knob downward, whereupon the rod connectingthe control knob to the device that compresses the small flexible tubewhere it crosses the shaft (or an extension of the shaft) is compressed.By varying the extent to which the control knob is depressed, the usercan vary the compression of the rod, which acts proportionally againstthe spring of the device that compresses the small flexible tube.

[0020] Liquid spreading brooms available on the market, which have beenpreviously described, present certain drawbacks that become apparentafter a short period of use. These drawbacks render the broom itselfunusable or result in fairly costly repairs to return the device to itsoriginal working condition.

[0021] These drawbacks result from the fact that products designed to bespread on a floor are not simple liquids but consist of wax emulsions,which lose some of their own solvent into parts of their containers oralong the pathway leading to the floor or, as a result of polymerizationproblems, become so thick that they form colloid deposits or denseincrustations. This results in the obstruction of small openings and thegumming of joined parts whose function requires that they be separated.

[0022] Orifices must be cleaned with small rods to clear passages;joined parts that must be separated require the use of the appropriatetools since the force needed to unscrew threaded male and femaleelements is much greater than the force an operator can exercisemanually.

[0023] These efforts at cleaning and removal or unlocking not onlyrequire more or less lengthy periods of time and related costs, butinvolve the risk of breaking the coupled parts themselves, which canrender the entire broom dysfunctional.

[0024] One objective of the present invention is to supply a broomprovided with a reservoir having a regulator for controlling the flow ofliquid in said reservoir, in particular a fluid wax, which eliminatesall the drawbacks found in currently marketed brooms equipped with areservoir with a liquid flow regulator, by introducing innovativefunctional and structural concepts and also reducing production andhandling costs.

[0025] Innovative solutions are introduced by the current patent toeliminate the above drawbacks.

[0026] The first innovation involves the discharge orifice provided onthe bottom of the reservoir. Here it is realized, in continuity with thereservoir mold, by means of a robust tubular appendage equipped with asufficiently large opening.

[0027] In the event of incrustations that are liable to obstruct theopening, this facilitates access to the opening and avoids the risk ofbreaking the tubular appendage, which would render the reservoir itselfunusable. For attaching the small flexible tube that transports theliquid to the floor, a small tubular connector has been provided, whichis removably nested on the extremity of the tubular appendage of thereservoir. The tubular portion of this small connector can be easilycleaned because it is possible to introduce a small cleaning rod fromeither end of the tubular section, or by following the short length ofthis tubular section. Even if the tubular appendage of the smallconnector should break, this poses no problem with respect to the broombecause said small connector consists of an inexpensive replaceable partand, as an added precaution, a second connector can be supplied with theoriginal broom.

[0028] The second innovation involves the mounting of the reservoircover.

[0029] At present the cover, which is equipped with a central tubularcavity running along the length of the broom shaft, is attached to thereservoir by means of a threaded connection. According to the innovationintroduced by the present patent, the cover is no longer screwed inplace but pressed on with suitable force using appropriate means.Consequently, whenever the cover must be removed, even if incrustationsshould occur, causing it to stick to the reservoir, the user only needsto overcome frictional forces and only such force needs to be applied asis accessible to any user.

[0030] Appropriate means provided for securing the upper opening of thereservoir, using the non-screw cover, can be snap-on elements consistingof, for example, (elastically) rotatable articulated arms alongappendages of the cover, which arms present a hook-shaped extremity forgripping associated appendages present on the outer surface of thereservoir.

[0031] Another innovation present in the current patent involves thefabric support, connected in oscillatory manner to an end of the shaftcarrier. This support, generally cylindrical in shape, is covered with awraparound mop on which the edges of the longitudinal opening areprovided with snaps. To prevent the mop from slipping or turning aroundits cylindrical support when it is moved across the surface of thefloor, this support is provided with rigid fins radially arranged alongits upper surface of revolution, said fins being coplanar with thecentral stirrup together with the articulated connector joined to thefork-shaped extremity of the shaft carrier.

[0032] Another innovation involves the method of attaching the controlknob, designed to control compression of the small flexible tube, on theupper extremity of the rod.

[0033] Currently, on existing brooms, the control knob and the upperextremity of the rod are attached by means of a screw engaged in theplastic of the control knob, said screw acting superficially on the rodaxially threaded into the control knob by pressing it against the wallof the hole. In this way, the rod is secured by taking advantage solelyof the mechanical adhesion between the wall of the hole in the controlknob and the surface of the rod.

[0034] The movement transmitted from control knob to rod over relativelylong periods of time compromises their mutual attachment as a result ofthe fragility of the threads in the plastic material of the control knobaccommodating the transverse screw. The impossibility of procuring asecure connection, while eliminating possible sliding of the rod inrelation to the screw exercising pressure, compromises efficient flowcontrol through the small flexible tube because compression of the tubedepends on perfect positioning of the rod. The solution to this problemwas achieved by realizing a transverse cavity in the control knob, saidcavity intersecting and terminating at the axial hole present in thecontrol knob into which the rod is inserted. A locking element(preferably having a prismatic cross-section) is inserted into thiscavity, having a transverse hole corresponding to the transversecross-section of the rod and a threaded axial hole into which a screw isthreaded.

[0035] When the rod is inserted into the control knob, it enters andextends beyond the transverse hole housing the locking element. Once therod is in place in the correct position, the rod is tightened with theaxial screw in the locking element so that this element becomes anintegral part of the rod.

[0036] The coupling thus realized between the control knob and the rodis maintained because, with the locking element mounted on the extremityof the rod, a form of expansion is realized, which distributes the axialforces of the rod along the surface of the seat of the control knob inwhich the locking element is located.

[0037] This innovation facilitates the assembly of the various parts ofthe broom during construction as well as removal of the rod from thecontrol control knob located on the top of the shaft whenever the broomneeds to be cleaned or should any maintenance need to be performed onthe broom, without compromising the quality of the coupling.

[0038] Another innovation concerns the manner in which the small tube iscompressed. Whenever compression occurs, complete blockage of the flowof liquid in the reservoir is assured without any possibility ofunwanted flow, which could be harmful during use of the broom or couldcause the reservoir to drain when the broom is not in use.

[0039] To this end the invention proposes a small nose realized with theexact bend radius for the type of flexible tube to be compressed andensures that the small nose compresses the flexible tube in the middle,without causing any asymmetry.

[0040] The small nose is centered on the flexible tube by realizing aprismatic coupling between the piston bearing the small nose and thesleeve in which the piston slides, or by enlarging the base of the ribwhose summit forms the small nose, in such a way that, when it is nearcompression position, this base automatically centers the nose byresting on the edges of the opening of the sleeve in which the pistonslides.

[0063]FIG. 24 is a representation of three parts in proximity,specifically, the upper part of a normal reservoir, an annular element,and a type of cover lacking threads. The three-piece assembly can beused to remove the cover while ensuring closure of the reservoir mouth,without having to unthread the assembly, whenever the liquids used mightcause clogging and incrustations. The summit of the reservoir has anannular element whose interior is provided with threads and whoseexterior with appendages or a connecting edge having a bottom-facingundercut. The cover lacks an internal thread and has, on its outersurface, at least two levers elastically articulated on this surface,whose lower arms have hook-shaped extremities. The attachment of thecover and the annular element does not require any reciprocal rotationsbut is achieved through translation of the cover, which, once pressedtightly against the summit of the annular element, remains securelyjoined to the appendages of the annular element by means of the smallhook-shaped arms on the levers with which it is equipped. To remove thecover the user acts on the upper arms of the levers, rotating them in adirection opposite the previous tightening direction, the upper armscausing the lower arms to move outward, thus disengaging them from theappendages on the annular element.

[0064]FIG. 25 is a drawing of the cover and the annular element in FIG.24 in their attached position.

[0065]FIG. 26 is a drawing, seen from the front, of the small noseprovided for compressing the small flexible tube (not shown in thisdrawing), which exits the opening present in the lower extremity of thesleeve connected to the shaft. The drawing also shows that said openingpresents, in its uppermost portion, a semicircular profile correspondingto the outer diameter of the small flexible tube, which, as previouslyindicated, is not shown here, and which, after an initial section,increases near the bottom, its edges being curvilinear in shape. Thedrawing also shows, at the base of the rib whose upper part constitutesthe small nose, the saddle, whose sides come into contact with the edgesof the opening of the sleeve as it moves upward, thus centering thesmall nose within the semicircular profile that defines the summit ofthe sleeve opening. Because of this embodiment of the sleeve opening anduse of the saddle at the base of the rib constituting the small nose,the control knob located at the top of the shaft (when engaged by meansof the enlarged portion of its hollow with the key in its respectivesleeve) can be turned without applying excessive torsion to the rod,whose lower part is connected to the piston provided with the smallnose.

[0066]FIG. 27 illustrates the manner in which the small flexible tube iscompressed by the small nose against the edge found at the top of theopening of the sleeve joined to the shaft whenever the small nose iscentered. The illustration shows that the interior wall of the smallflexible tube presses against itself in uniform fashion, which resultsin complete closure of the tube.

[0067]FIG. 28 illustrates the manner in which the small flexible tube iscompressed by the small nose against the edge on top of the opening ofthe sleeve connected to the shaft whenever the small nose is notcentered. The illustration shows the asymmetrical deformation of thesmall flexible tube. The interior wall of the small flexible tube is notcompletely compressed against itself, leaving a slight opening. Such anopening, even when very small, allows the escape of liquid, which flowsdown from the reservoir, resulting in obvious operating problems,including unwanted discharge of the reservoir when the broom is notbeing used or is being stored.

[0068]FIG. 29 is an elevation view of the mop support. It shows that thesupport comprises two fins on the sides that rise from the top andassume the same position as the stirrup provided for attaching the shaftcarrier. A part of each of the fins is reduced in height in the centerto provide a passage for the male stud used to secure the mop. The finsserve to prevent the mop, once wrapped and snapped in place, fromturning or moving in translation with respect to the support.

[0069]FIG. 30 is a top view of the corresponding mop support shown inFIG. 29.

[0070]FIG. 31 is a side view of the mop support shown in FIG. 29.

[0071]FIG. 32 is a schematic representation that illustrates how thesnap system for securing the mop around its support is realized withrespect to the openings present in the fins.
